In the crazy world of Sandy Hook conspiracy theories, this one may be the worst yet. (Maybe you’ve already heard some of the others, like the one about fantasy ties between the gunman’s family and the LIBOR banking scandal and a related theory about the Aurora shooting and the “Dark Knight Rises.”) Most of the theories are really pieces of a larger meta-theory: that the Sandy Hook shooting was a hoax, perhaps by the Obama administration, designed to stir demand for gun control.

In the latest angle, theorists think they have found “absolute proof” of a conspiracy to defraud the American people. “You reported in December that this little girl had been killed,” a reader emailed Salon in response to a story. “She has been found, and photographed with President Obama.”

There are dozens of websites, blog posts and YouTube videos extolling the Emilie Parker hoax theory. If you Google her name, the very first result is a post mocking her father for crying at a press conference after the shooting. One popular video, which already has 134,000 views, was made by the producers of a popular 9/11 Truther film. “Just as the movie ‘Operation Terror’ shows the 9/11 attacks were a made-for-TV event, so too were the mass shootings … There can be no doubt that Sandy Hook was a staged event,” the narrator intones. He goes on to say that the adults who participated in the media coverage of the shootings “should be prosecuted as accessories after the fact in a mass murder” — i.e., the parents whose children were murdered in the massacre should be thrown in prison.

But the hoax theory has even earned the backing for some presumably more credible sources. James Tracy, a tenured professor of communications at Florida Atlantic University, sparked controversy this week after he wrote a blog post suggesting the parents were “crisis actors.” “While it sounds like an outrageous claim, one is left to inquire whether the Sandy Hook shooting ever took place — at least in the way law enforcement authorities and the nation’s news media have described,” he wrote.

Websites owned by Alex Jones, the conspiracy theory pundit who helped start the 9/11 Truther movement and has millions of readers, are a virtual one-stop shop for Sandy Hook “false flag” miscellanea. So far, mainstream conservative figures haven’t hopped on board, though Gun Owners of American head Larry Pratt told Jones this summer that he thought there was a good chance the Aurora massacre was perpetrated by government agents.
